摘　　要：以顺式-1,2,3,4-环戊烷四羧酸(H_4CPTC)、4,4′-联吡啶(bipy)及水合醋酸铜为原料,通过溶剂热法合成了配合物{[Cu_2(H_2CPTC)(bipy)_2]·(C_4H_8O_2)_(0.5)·(H_2O)}_n(C_4H_8O_2=1,4-二氧六环).用X-射线衍射法测定了配合物的晶体结构.结果表明,配合物属于三斜晶系,空间群为P-1,晶胞参数a=1.053 4(2)nm,b=1.282 9(3)nm,c=1.288 4(3)nm,a=65.87(3)°,β=106.327(10)°,γ=86.29(3)°.该配合物由4,4′-联吡啶桥联中心金属铜离子形成一维链状结构,链与链之间通过配体相连形成二维结构.A novel copper（Ⅰ）complex,{[Cu_2（H_2CPTC）（bipy）_2]·（C_4H_8O_2）_（0.5）· （H_20）}_n（C_4H_8O_2 =1,4-dioxane）,was synthesized by solvothermal method from copper acetate monohydrate,4,4＇-bipyridine and cis,cis,cis-1,2,3,4-cyclopentanetetracarboxylic acid （H_4CPTC）.The crystal structure was determined by X-ray diffraction technique.The complex crystallized in the triclinic system with space group P-1,a=1.0534（2）nm,b=1.2829（3） nm,c=1.2884（3）nm,a=65.87（3）°,β=106.327（10）°,γ=86.29（3）°.The copper ions were connected by a 4,4＇-bipyridine ligand to form a 1D chain as the assembly unit,which was further linked by H_4CPTC ligand to generate the final two-dimensional structure.Fluorescent spectrum of the complex exhibits emission peaks at 487 nm.
